Predictive layer: sensor trends, not just fault codes

[Goodnight77]

Goal: move from reactive (fault codes) to predictive (before failure).

• Today TORQ reacts to fault codes: it owns the expensive minutes AFTER a fault
• Add a predictive layer: ingest sensor telemetry (vibration, temperature), detect anomalies via thresholds or ML, and raise a fault before the machine trips
• Feeds the same downstream pipeline (diagnose -> work order -> dispatch)
• Large scope; future enhancement, not part of the current pitch
